I went from 2 T1 mixers to one T8 for the possibility to use 8 XLR's. It works great, even though the effects work a bit different compared to the T1's.
But, the built in tuner is very unstable and flickers all over the place, still centered around the actual pitch though. This is when I line my K&K equipped instruments. No hum or noise. Good sound and good signal, but still very hard to spot the pitch.
Yes, I have done all of the suggestions above (I have been using the T1 for many years). I did a firmware upgrade when the mixer was bought in May, but I will check the version again. Think it is the latest, though..
I love the built in tuner because it is (normally) very unforgiving and always available when gigging. Anyone else experiencing this tuner flickering?
I spent some time with the T8S tuner function this evening. I found some interesting things.
The amount of flickering varies from guitar to guitar
The display is more stable with my electric guitars than the acoustic guitars
On my acoustic guitars, muting the other strings (not the one I'm tuning) makes the display more stable. If the other strings are open and resonating, this seems to cause the indicator to move around more.
If the indicator is jumping around, I can make it more stable by turning down the volume on the guitar
With the T1, when people had trouble with the tuner it was often because the signal hitting the tuner wasn't strong enough to be detected properly
With the T4S/T8S the tuner is sensitive and the display seems faster than the T1. By turning down the volume a bit, I think the tuner detects more of the fundamental note and fewer overtones and the other strings.
